To all whom it may concern:

Be it known that I, PETER A. RASMUS, a citizen of the United States, residing at Paxton, in the county of Ford and-State of Illinois, have invented a new and useful Improvement in Automatic Automobile Turn- Tables, of which the following is a specification.

This invention relates to certain new and useful improvements in automobile turntables, the, object being to provide an automatic turntable in which the power for operating the same is derived from the wheels of the automobile when the automobile is in position thereon. I

A still further object of my invention is to provide a turntable which is exceedingly simple and cheap in construction, and one which is especially adapted to be used in public and private garages or any other place where it is desired to turn .the automobile partially or wholly around in a limited space.

A still further object of my'invention is to provide a turntable in which the operating mechanism is thrown into gear by the machine passing upon the same, in such a manner that the power for driving the turntable will be derived from the wheels of the automobile in such a manner that the turntable can be turned without the driver of the machine leaving his seat.

Another object of my invention is to provide a brake in connection with the turntable, whereby the same can be stopped at any desired point, the brake being so arranged upon the turntable that the same can be readily operated by the driver of the machine without leaving his seat.

A still further object of my invention is to provide novel means for revolving the turntable, which comprises a pair of worm gears slidably mounted upon opposite sides of a centrally arranged gear in such a manner that one of said worm gears will be thrown into mesh with said gear, and the other thrown out of mesh, whereby the gear out of mesh will be thrown into mesh by the next automobile passing upon the turntable after the first machine has passed off of the same.

With these objects in view, the invention consists in the novel features of construction, combination and arrangements, of parts hereinafter fully describe and pointed out in the claims. 1

In the drawing forming a part of this specificatiohz-Figure 1 is a top plan view partly broken away of my improved automatic turntable showing the operating mechanism in the position it assumes whena machine is upon the same ready to be turned. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a section taken on line 3 3 of Fig. 2. Fig. 4 is an inverted plan View of the turn table. Fig. .5 isasection taken on line 5-5 of Fig. 1, and Fig 6 is a section taken on line 6-6 of Fig. 1.

In carrying out my improved invention, I employa bearing pin A which is secured to the floor of the garage at the desired point,

and on which is mounted a cup shaped bearing B secured centrally to the under side of a circular turntable C which can be formed of any suitable material, and is provided with spaced guard rails D for guiding the machine in position thereon. Arranged at opposite pointt on the table are gang planks E E, and while I have only shown a pair of these gang planks, it is of course understood that a table could be entirely surrounded by the same in orderto allow the machine upon the same to pass oflz' after being turned only partly around.

Secured to the floor under the table C is a ring F having an upwardly projecting flange provided with a lateral toothed portion F forming an'annular gear for the purpose later described. The ring F is secured to the floor by any suitable means, and *forms' a track for casters G carried by the table C in order to support the table firmly, in such a manner that the same can rotate freely the central pin and cup A and B forming means for holding the table in order to prevent the same from moving in any wa By thisconstruction the turntable can lie rotated very easily and in such a manner that all danger 40 prevent the same from moving: until the driver of they machine is ready, brake P, the

e revoluble movement for the purpose desired. a p The rollers H "table adjacent the extend rollers and I which are carried shafts J and K mounted in suitable bearings L and M secured to the under side of the slots, and the bearings L allow the shafts to have a sliding and are idle rollers and the rollers -I formpower rollers which are'fixed-to'the a are provided with worm gears MT 1 .-m'esl1 ',with the annular gear F of .the ring F that when the drive wheels of the automobilet passupon be "fIC6d away rotated by the shafts K in such a manner adapted to in such a manner that the turntable will be rotated by the worm gears when the power rollers are revolved. r

The. shafts K carrying .the worm gears I and-power rollersare connected together by that when an automobile turntable 'itfwill be forced lnto engagement and the other disengaged. By this arrange-l slidab ly, mountedabars O which are mount ed in suitable-bearings O securedtothe under side of the turntable, and the ends of v receive the ends of said barsare provided with bearin s- O to in such a manner that when onevof the worm v gears isfforced into enga ement with the "annular gear, the'other Wlll 'beiforced outoscillated by the that when the table is worm" of engagement so other worm V mentone of theworm gears is always 'in driver; of the machine without 'mesh and the other out of mesh ready to be thrown into mesh by the'automobileif In order to provide means forstopping the turntable at the desired point and to I provide .a hand lever of which extends out through the turntable into such a tion that it can be" readily gras ed by the eaving his seat, and it will be seen that by this .con

stru'ction the driver after passing upon the platform releases the brake andv power; of

the driving wheels of. the machine which operated the worm gear sofas to cause the worm gear to rotate. i What Ivelaim is: 1. 1A turntable having gearin ing the same driven by the w 5 eration and out ofoperat1on by the'-,vehicle I passingvupon thesame;

, ,2. A turntable having out of operationby thevehicle passing upon. 'th'esameh 3. Ajrevoluble-turntable for automobiles means foridriving the same, sald means being thrown into and the respective s lafts K gear in mesh, thegearwill be in such a position passes upon'theposi rollers arranged in said slots,

. ing themovable rollers provided with worm gifor ;operat-' eels of the thrown intokop having means for driving the same thrown intooperation and operated by the vehicle passing u on the same and out of operation .by'the veliicle passing off of the turn table.

4. The combination with a revolubly mounted platform, of a fixed gear arranged under 'said platform, worm gears co-acting means operated by the the platform for movvehicle passin "upon 'ing one of sai wormgears into engagement with said fixed gear and rotating said gear. v 5. Anautomatic turntable comprising a rev'oluble platform, an annular gear arrangedunder said platform, revolubly and slidably mounted worm gears co-acting with the opposite sides of said fixed gear, and means operated by the passage of a vehicle upon saidplatform' for throwmgone of said worm gears into mesh. with the fixed gear and rotating thesame'and disengaging the other worm gear. a i p 6. In an automatic table, the combination with an automatic platform,of a fixed gear arranged. under said platform, a revolubly and slidably mounted worm gear co-aeting with said fixed gear, and 'mea'ns operated by the'passage of a vehicle'uponsaid platform for, throwing said worm gear into ens gagement with the samew i a I 7.
